Install the rod and piston group in the engine with the part number of the forging for the rod assembly to the rear of the engine. The rear of the engine is the flywheel end of the engine. Lubricate the rod and piston group with clean engine oil before you insert the rod and piston group into the block.
1 1 549-8397 Piston Ring Install the top piston ring with the side marked "UP-1" toward the top of the piston. The blue colored stripe faces to the right of the ring end gap.
When the new top piston ring is installed in a cylinder liner bore with bore size of 115.025 0.250 mm (4.5285 0.0098 inch), the clearance between the ends of the piston ring is 0.60 0.10 mm (0.023 0.003 inch).
Thickness is 3.5 mm (0.14 inch).
2 1 549-8398 Piston Ring Install the intermediate piston ring with the side marked "UP-2" toward the top of the piston. The white-colored stripe faces to the right of the piston ring end gap.
When the new intermediate piston ring is installed in a cylinder liner bore with bore size of 115.025 0.250 mm (4.5285 0.0098 inch), the clearance between the ends of the piston ring is 0.80 0.10 mm (0.030 0.003 inch).
Width of groove in new piston body assembly for intermediate piston ring is 3.080 0.010 mm (0.1213 0.0004 inch).
